11. usic enthusiast who is not willing to make a compromise in a small living room By the cardioid radiation characteristics within the frequency range from 35 through 250Hz the reflections on the back walls behind the speaker can be minimised In addition the transfer characteristic can be matched to the acoustical conditions of the reproduction room as well as to the set up situation by an integrated room matching filter The total directivity index of the monitor was optimised for listening distances between 1 and 2 60m 3 3 and 8 6 ft As the bass system a very linear 200 mm 8 long throw driver in a cardioid cabinet is employed delivering excellent impulse fidelity Due to the special construction a low frequency reproduction is possible that is not expected from such a small cabinet Therefore the RL944K is a real full range speaker and in an outside broadcasting van an additional subwoofer can be spared The 100mm 4 cone is mounted together with the 19mm 3 4 dome tweeter coaxially in front of the bass system allowing a precise steering of the focal perspective As a result a realistic and steady spatial performance of the sound image around the listening position is achieved with high homogeneity and smallest possible colouration By the great consequent optimisation for short listening distances the RL944K allows realistic depth arrangement even in outside broadcasting vans and facilitates correct miking Therefore the RL944K is a pre
